Current reports on "The Joker" in the "Batman vs. Superman" film links actor Callan Mulvey to the villain character. However, the "300: Rise of an Empire" star remains tight-lipped on the subject whenever asked if he will portray the scary role in the upcoming superhero film.

According to the HNGN report, an unnamed TMZ employee asked Callan Mulvey what the actor can share about the "Batman vs. Superman" film. The 39-year-old actor responded that he cannot talk or say anything about it because he has sworn secrecy.

"You're going to have to wait and see," Mulvey teased in the recent TMZ interview. Last April, film director Zack Snyder has confirmed the addition of Callan Mulvey, Holly Hunter and Tao Okamoto to the cast members of the "Batman vs. Superman: Dawn of Justice" film but did not reveal the characters they will be portraying.

The MLive report noted how director Zack Snyder praised Callan Mulvey for his acting skills while they worked in the film titled "300: Rise of an Empire. "He's a fantastic actor and I'm looking forward to having the chance to work with him again," Snyder declared in the Entertainment Weekly report during the cast announcement of the film last April 3.

The reports on Callan Mulvey's "The Joker" role in the "Batman vs. Superman" film started a couple of days after actor Adrien Brody expressed his interest in portraying the villain character. Cinematographer Larry Fong has also teased the fans about "The Joker" when he posted an image on Twitter but the "Batman vs. Superman" production team has given any statement to confirm or deny the appearance of the character in the film.
